2 apples in the partly filled tray, 11 tents are needed for all the children
(50-25)/2
25/2
12.5
25+12.5=37.5
I believe it is 3x+21 but i could be wrong :/ my explaination is -3 • -X would be +3x because it was distributed and -3 • -7 would be +21
There are 2 x intercepts, x=-4 and x=-1
The answer and explanation in the pic below
Good luck,!
